Every ecosystem is an intricate composition of abiotic (non-living) and biotic (living) aspects. The Bluefin Tuna lives in the top-most layer of the ocean, called the Pelagic Zone, and exists among many other sea creatures that share the oceanic ecosystem.

List of Abiotic/Biotic Factors

Abiotic Factors
Biotic Factors
Sunlight: (Pelagic) Zone
Crustacean (Prey for Juveniles)
Aerial Exposure (90 Percent of the World’s Oxygen is Made In This )
Herring (Prey)
Temperature (Subtropical, Temperate Waters) Can go from 104 to 27 Degrees F
Bluefish (Prey)
Depth (Can Dive to 914 Meters)
Coral (Buffers from waves and prevents erosion, protect ecosystem)
Nutrients (Most Phytoplankton Grow Here Because of the Sunlight)
